    Intel Trusted Execution Engine Interface problem causing BIOS update to fail?


      On my NUC DN2820FYKH running Windows 8.1 / latest drivers / BIOS v48 I have the following symptoms:

      • In the Device Manager the Intel Trusted Execution Engine Interface device is marked with a yellow exclamation mark (!), and the status is “This device cannot start (Code 10)”. STATUS_DEVICE_POWER_FAILURE.
      • In the Event log I find the error “Intel Trusted Execution Engine Interface has failed to perform handshake with the Firmware”.
      • Whenever I try to update the BIOS, to the latest v50, or to a previous version, I get the error message “Flashing image for Intel Management Engine firmware …(Failed!)
        Flash update failed
        Technical information: (0x8000000000000003, 0)”

      My first guess was that I had a hardware fault in the Intel MEI component, but after having performed a system refresh of a similar NUC for a friend, including a BIOS update from v34 to v50, and having discovered the same symptoms in the Device Manager, I now suspect something else! Could it be that the BIOS update to v48 or v50 has made the MEI component non-operational?

      Help appreciated, how do I get back to a fully functional NUC with the capability update the BIOS in the future?
